Duration of antigenaemia in Au-positive viral hepatitis.

Abstract

The duration of antigenæmia was investigated in six patients with Au‐positive hepatitis and found to vary according to the method of detection employed. Using the most sensitive test, complement fixation, antigenæmia was detected for a mean of 47 days after the onset of illness. In four of the six cases the antigen became undetectable only after clinical and biochemical recovery from the disease.
